Devil's Relief is a powerful combination of herbal tinctures formulated together with Devil’s Claw, a herb native to Africa. Devil's Relief helps ease stiffness associated with limited flexibility. The older horse may particularly benefit from Devil's Relief, not only because it directly targets stiffness, but also because the bitter action of this formulation can help stimulate the digestive system, and poor digestion and absorption are often associated with old age. Devil's Relief can be fed to all horses and ponies with the exception of pregnant mares.
